Application filed April 2, 1913. Serial No. 758,370.

To all whom it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States,and resident of Stonington, in the county of New Lon don and State ofConnecticut, have invented a new and useful Improvement in Static-Electricity Dissipators for Paper Webs or Sheets, of which the followingis a specification.

Myinvention relates to improvements in static electricity dissipatorsfor paper webs or sheets, and is directed to that type of dissipator orneutralizer in which the electricity is removed from the web by slightlymoistening the same, also providing 'a static discharge through amoistened wick contact. i

The object of this invention is to provide means for bringing the paperand dissipator into and out of coaction, and more particularly toelectrically operated means under the control of the printing pressstarter whereby the dissipator and paper are brought into coaction whenthe press is running and out of coaotion when the press is stopped. V

This invention is directed more particularly to means for moving the webinto and out of contact with the moistener of the dis sipator while mycopending application filed of even date herewith, Serial N 0. 758,369now Patent No. 1,244,015 is more particularly directed to means formoving the moistener of the dissipator into and out of contact with theweb.

If the web is left in contact with the moistener of the dissipator whenthe web is still, the paper will become saturated to such a degree as tomaterially weaken or break it. This invention contemplates means foravoiding this trouble. 7

A practical embodiment of the invention is represented in theaccompanying drawings, in which,

Figure 1 represents inside elevation so much of a folding machine andprinting press as will give a clear understanding of the construction,location and operation of the several parts of my static electricitydissipator, the parts being shown in full lines in their operativeposition and in dotted lines in their inoperative position, and

Fig. 2 is a transverse section taken in the plane of the line AA of Fig.1.

The printing press starter is denoted by 1, which starter may be of anywell known or approved construction capable of controlling the operationof the press. The web 2 is shown as passing around a series of rolls 3,

4, 5, 6, on its way from the press to the formers 7 of i the foldingmachine. The rolls 3 and 4 are located upon the same side of the web 2and are mounted in oppositely arranged pairs of arms 8, 9, of acompensating lever pivoted at 10 in the main frame 11. The compensatingleveris so mounted that the rocking of the lever will move the positionsof the rolls- 3 and 4 to change the path of the web 2, without changingits tens1on. l

The moistening wick is denoted by 12,

and its fountain by 13, which fountain is a supported by the main frame11. Liquid is supplied from a stationary reservoir 14 mounted on thebracket 13 secured to the main frame 11, through a feed pipe 15 havinggasuitable controlling cook 16.

lectrically operated means under the control of the printing pressstarter are pro .vided for operating the compensating lever to move theweb 2 into and out of contact with the inoisteningwick 12.- Thiselectrically operated means includes an electromagnet 17 connected tothe printing press starter through the wires 19, 19. The armature 20 ofthe electro-magnet is connected by a rod 21 to an arm 22 of thecompensating lever, said lever being provided with another arm 23 havinga weight 24 tending to swing the compensating lever to move the web 2away from the moistening wick 12. The armature 20 is shown as providedwith an arm 25 which is arranged to engage a stop 26 on the main framefor limiting the movement of the compensating lever. A ground wire 27leads from the fountain 13. In operation, when the starter controllinglever 28 is swung into position to stop the press, the electro-magnet 17will be deenergized causing the web 2 to be moved away from its contactwith the moistening wick 12, by the compensating lever. This isaccomplished Without lessening the tension on the web. When thecontrolling lever 28 is moved into position to start the press, theelectro-magnet 17 will be energized, thereby moving the compensatinglever against the influence of the weight 24, in a direction to causethe rolls 3 and 4t to bring the web 2 into contact with the moisteningWick 12. The electr c-magnet is preferably so connected to the printingpress starter that the magnet will not be energized until after thepress has attained a speed sufficiently high to prevent undue saturationof the web by its contact With the moistening Wick.

It is obvious that the means shown herein for automatically bringing theWeb into-and out of co-action with the dissipator is only one of manydifierent forms which might be shown for accomplishing this result;hence I do not wish to limit myself to the particular means herein shownand described.

While I have shown this invention in con nection With a running Web, itis to be under'stood that I Wish to include sheets as Well. i
